摘要： The present invention provides a bridged, direct-attached storage device that can be secured and work with any host system. In one embodiment, the storage device is configured with a secured user area and an unlocking mechanism for access to the secured user area. The storage device may comprise a translation module having a bridge that presents multiple logical units to a host. In addition, the storage device may comprise a controller having its own encryption engine to encrypt the entire user area of the storage media. In one embodiment, the storage device presents the unlocking mechanism via a second logical device as a read-only device, such as a CD/DVD-ROM, or virtual CD device. The secondary logical device comprises executable code, which allows the user, for example, to enter, change, or remove the password and unlock the user area.

摘要： A data storage system is disclosed comprising a non-volatile memory and a first interface operable to receive a write command from a host, the write command comprising a host write data block having a host logical block size. A block mapping bridge divides the host write data block into a plurality of transfer data blocks, wherein each transfer data block having a device logical block size smaller than the host logical block size. The transfer data blocks are transmitted through a second interface to control circuitry that accumulates the transfer data blocks into a physical data block having a device physical block size equal to a first integer multiple of the device logical block size, wherein the host logical block size is a second integer multiple of the device physical block size. The physical data block is then written to the non-volatile memory.

摘要： A method of aligning a partition of a data storage device to a boundary of a physical data sector is disclosed. The data storage device comprises a non-volatile memory comprising a plurality of physical data sectors, wherein each physical data sector comprises a plurality of logical data sectors. A partition map is read from the non-volatile memory, wherein the partition map identifies a partition comprising a number of logical data sectors. A number of logical data sectors in each physical data sector is determined. Whether at least part of the partition aligns with a boundary of a physical data sector is determined. When at least part of the partition does not align with a boundary of a physical data sector, at least part of the partition is moved to align at least part of the partition to a boundary of a physical data sector.
